Materials reflecting the level of gas processing technology abroad (in the USA, Canada and other countries) are summarized. Technical characteristics and performance indicators of various types of equipment (compressor, pump, mass and heat exchange, etc.) with indication of manufacturers are given. At the same time, special attention is paid to equipment that is promising for use at domestic gas processing plants. Equipment for small-sized gas gasoline plants is described. The book is intended for engineering and technical workers (researchers, designers, operators) of the gas, oil refining and petrochemical industries.
